Name: Authentication Bypass by Primary Weakness

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.

Allgemeine Informationen

Einführungsmodi

Implementation : REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Referenzen Beschreibung

CVE-2002-1374

The provided password is only compared against the first character of the real password.

CVE-2000-0979

The password is not properly checked, which allows remote attackers to bypass access controls by sending a 1-byte password that matches the first character of the real password.

CVE-2001-0088

Chain: Forum software does not properly initialize an array, which inadvertently sets the password to a single character, allowing remote attackers to easily guess the password and gain administrative privileges.

Hinweise zur Schwachstellen-Zuordnung

Begründung : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Kommentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Hinweise

Most "authentication bypass" errors are resultant, not primary.
